Mickey Harris (January 30, 1917 - April 15, 1971) was a pitcher in Major League Baseball who played for the Boston Red Sox (1940-41, 1946-49), Washington Senators (1949-52) and Cleveland Indians (1952). Harris was born in New York, NY. He batted and threw left handed.

Though plagued by chronic arm problems, Harris helped the Boston Red Sox to win the 1946 American League pennant in route to the 1946 World Series against the St. Louis Cardinals.

Harris debuted with the Red Sox in 1940. He joined the starting rotation in 1941, along with Dick Newsome, Charlie Wagner, Lefty Grove and Joe Dobson. Harris responded with a 3.25 ERA and 111 strikeouts (8th and 5th in the AL, respectively), and his 8-14 record could have been even better with reasonable run support. After the season, he was drafted into the Army.

After being out for four years, Harris compiled a 17-9 record in 1946, as the Red Sox ran away with the pennant. In May, Harris posted eight consecutive victories, including two in relief in two days. He was named to the AL All-Star team in the same season. After that, Harris increased arm troubles and was traded to the Senators in the 1949 midseason.

In 1950 Harris led the AL pitchers in saves (15), relief appearances (53) and games finished (53). He went to Cleveland in 1952, his last season in the majors.

In a nine-season career, Harris posted a 59-71 record with 534 strikeouts and a 4.18 ERA in 1050.0 innings pitched.
